von Grumbach (†1564) ensured Groot Terhorne Castle until 1879 as the family seat in the Netherlands. The Frisian line was made a member of the Dutch nobility by a Royal decree of King William I of the Netherlands on August 28, 1814. Henceforth, the Dutch version thoe Schwartzenberg en Hohenlansberg was applied for this branch of the family. The Prussian Line was established as a cadet branch of the Frisian line with Georg Baron thoe Schwartzenberg en Hohenlansberg (1842–1918), who served as a Rittmeister in the Imperial German Army. He and his descendants were made members of the Prussian nobility by an Imperial decree, issued by Emperor Wilhelm II, and are entitled to carry the German title Freiherr. Imperial immediate estates The Schwarzenberg family held three Imperial Immediate Estates in the Holy Roman Empire. By coincidence the coat of arms of the Princely Landgraviate of Klettgau and the Earldom of Buchan in Scotland are the same. The Klettgau coat of arms can be found in the left heart shield of the Schwarzenberg coat of arms.
